ok well i thought i had a decent handle on the wiring i got my obd1 ecu plugs and started converting the two over well whoever had the shell last did a rack of repinning and i dont know what kind of motor he had in there i looked up possibilities but the way its wired i dont think it worked out for him maybe he gave up o the swap and never had it running so pretty much im gonna cut off the obdo plugs and just go from there anyone have some advice has to how i can trace down wires some of them theres only one color of it so thats a given but like all the main relays does it matter if they get switched up and the ignition has three of the same whats the easiest method of executing this prolem, maybe i could get the ecu side of the harness and just trade it out right? anyone know where i can get one

De-pin the plugs and trace them to the ECU.

Check wich ECU is in there, find the matching pin out diagram.
Use the multimeter to see wich pin is wich.

There's only like 6, so that's fairly straightforward.

the clips were cut off and the wires were all crazy i couldnt find the right diagram i looked up nothing matched and i can use volts yet because batt not installed and ignition is a mess i think im gonna try and get a new ecu harness from a stock dx start fresh

a good job to do if you have the right tool! :lol:

thats what i plan on doing i have the stock ecu to pull the ecu clips from and the obd1 harness i just need the ecu side of the engine harness so i dont have to track down any wires i still need a dizzy too

You don't want the battery connected when you are doing a ohm's test anyway.
He's telling you to check continuity between the wires in the engine bay and the pins to the ECU.
Set a multimeter to the Omega symbol(ohms) and check for continuity.

i know how to do that i thought he ment amps where can i find out how many ohms are for what

 

[88rexproject]

if i try and test continuity between wires what exactly am i matching it to....the sensore itself or is there a diagram that wil tell me whats what

Ok its seems as if you are confused as to what a continuity test is.
Please let me explain.
Heres a little thing I drew up in MS paint to give you an idea.

Now imagine that this basic circuit diagram is a representation of a 89 crx dizzy circuit.
Now if your going to do a (ohm's test) or continuity test you would disconnect the ecu connector from the ecu ,and also you would disconnect the 10 pin dizzy connector from the dizzy.At that point you would verify you are testing the proper pins by matching the wire colors or the colors that are indicated in a diagram manual.
I made up a circuit color and named it GRN/WH(Green with a White stripe).
Basically to perform an Ohm's test take a meter(preferrably a DVOM=digital volt meter)and place one lead on the pin located in the ECU connector,and the other lead to the dizzy connector.If your circuit is good it should read as close to .000 as possible but there is a 5 ohm allowance as a buffer.
Now according to industry automotive standards 5 ohm or less is a "Good circuit".

I hope this helps you understand better.Any questions just ask...ok?
